Calculation Method of the Carbon Footprint of Products of Animal Origin Integrated with the Physiological Absorption of Carbon Dioxide: Calculation Example of the CFP of Mozzarella di Bufala Campana DPO

Received: 03 March 2023;  Published: 15 August 2023;  doi: 10.21926/aeer.2303044


The environmental impact of emissions appears to be increasingly important for food, particularly those of animal origin. The LCA (Life-Cycle Assessment) method, an internationally standardized method used to calculate the environmental impact of goods or services, in the carbon footprint, does not take into account the carbon set and consequently the subtraction of carbon dioxide by the plant biomass whether or not aimed at the production of food of animal origin. This methodology could overestimate the carbon dio [...]

Comprehensive Geriatric Assessment of Elderly Adults

Received: 23 March 2023;  Published: 14 August 2023;  doi: 10.21926/obm.geriatr.2303245


The geriatric population is increasing all over the world. Aging people have special health requirements and comprehensive medical checkups prevent physical, functional and mental decline during the aging period. This study aimed to examine the fitness level and identify problems with the well-being of elderly persons. In this context, the study also attempted to determine the relationship between socio-demographic factors and the health status of elderly adults. In this cross-sectional study, 168 elderly adults (≥ [...]

Burnout Among Special Education Teachers and the Role of Individual, Interpersonal, and Organizational Risk and Protective Factors

Received: 30 March 2023;  Published: 10 August 2023;  doi: 10.21926/obm.icm.2303033


Burnout is a syndrome commonly characterized by the three dimensions of Maslach and Leiter's model, namely emotional exhaustion, depersonalization, and lack of professional accomplishment. While burnout affects individuals in all professions, teachers are recognized as being at particular risk, a fact explained in the literature by the high level of relational demands inherent to the profession. During the pandemic and subsequently, these demands have even increased. Several studies have focused on the influence of [...]

“Welcome to Our World”: Experiences of Persons Living with Dementia Prior to and During the COVID-19 Pandemic

Received: 20 June 2023;  Published: 10 August 2023;  doi: 10.21926/obm.neurobiol.2303178


People diagnosed with dementia are experts on living with the disease, yet their perspectives are often overlooked in research and practice. The pandemic has amplified health inequities among older adults, but the impact of the pandemic on the lived experience of people living with dementia remains unclear. This qualitative study used a series of 2 virtual focus groups with people living with dementia (N = 7) to explore challenging situations and emotions experienced by community-dwelling people living with dementi [...]

Research and Application of Modified ZSM-5 for the Process of Alkylation of Oil Distillate Fractions

Received: 20 April 2023;  Published: 10 August 2023;  doi: 10.21926/cr.2303021


In the oil distillate fraction alkylation process, a modified Zr zeolite ZSM-5 was obtained and studied. The modification was executed using a method that impregnated ZSM-5 with a 5% solution of ZrOCl2∙6H2O. X-ray diffraction studies were conducted on zeolite ZSM-5, zirconyl chloride modifier ZrOCl2∙6H2O, and modified zeolite ZSM-5-ZrO2, which was calcined at temperatures of 200, 400, and 550°C. The results revealed that the phase composition of modified ZSM-5-ZrO2 zeolite samples varied depending on the calcinatio [...]

Carnauba Straw as Feedstock for Solid Biofuel Production

Received: 29 March 2023;  Published: 09 August 2023;  doi: 10.21926/aeer.2303043


Carnauba straw (Copernicia prunifera), residual biomass derived from wax extraction, was evaluated as a potential feedstock for bioenergy production. The characterization was carried out using elemental analysis, proximate analysis, Higher Heating Value (HHV), FTIR spectroscopy, SEM, and FRX. The carbonization, using a Muffle Furnace, was applied as a thermal conversion technique to improve the fixed carbon content, and preliminary densification was done to assess the potential for future production of briquettes.

The Psychometric Properties of the COVID Stress Scales in Korean University Students

Received: 13 April 2023;  Published: 07 August 2023;  doi: 10.21926/obm.neurobiol.2303177


The COVID-19 pandemic and its associated disruptions have significantly impacted university students’ lives worldwide. The COVID Stress Scale (CSS) is a 36-item self-reporting instrument designed to measure stress caused by the COVID-19 pandemic. This study purposed to examine the psychometric properties of the Korean version of the CSS for use with Korean university students. The study sample comprised 402 undergraduate students enrolled in a four-year private university in central South Korea. This cross-sectiona [...]

Joint Biodiversity Management Committees: A Mechanism to Manage and Conserve Eco-Regions

Received: 31 January 2023;  Published: 07 August 2023;  doi: 10.21926/aeer.2303042


Sasthamkotta Lake eco-region is a freshwater Ramsar site in Kerala, India. Eco-regions are ecologically and geographically defined larger land or water mass areas with a characteristic assemblage of the ecosystem and significant biodiversity. A decentralized and locally self-sustaining mechanism has been achieved in managing this eco-region by a participatory model through a joint Biodiversity Management Committee (jBMC) constitution. BMCs are custodians of the environment, and biodiversity, confined to a village/P [...]

Vascular Risks, Aging, and Late-Onset Dementia: Overlapping Etiologies Point to 'Scavenger Receptor'-Mediated Therapeutics

Received: 25 March 2023;  Published: 04 August 2023;  doi: 10.21926/obm.geriatr.2303244


Early changes in systemic vascular stiffness and endothelial function can contribute to altered cerebrovascular hemodynamics and impaired cognitive function; additionally, these vascular changes point to potential targets for prevention and treatment strategies in people with mild cognitive impairment. Although the pathogenic mechanisms underlying these vascular changes are heterogeneous and complex, one common feature is the development of cerebral blood flow (CBF) dysregulation, resulting in chronic cerebral hypo [...]
